In-house 24/7 team, hybrid model, or MDR? How to choose your ESET Inspect operations model
“In-house SOC or MDR?” is a question most frequently asked too early and framed incorrectly. Before answering which model is superior, more fundamental issues must be evaluated: what actual operational capacity can the organization sustain over time, month after month – even when a key employee takes leave or departs the company?
This article does not claim which model is universally best; that depends entirely on the specific organization. Instead, it provides a structured framework to evaluate whether managing ESET Inspect in-house 24/7, adopting a hybrid mode, or leveraging an external SOC via an MDR service aligns with your oragnization’s resources and operational needs.
When in-house management may be sufficient?
An internal SOC team makes sense when:
- There is more than one person capable of independent event triage and analysis in ESET Inspect. A single specialist – no matter how skilled – represents a single point of failure. Vacations, sick leave, or staff turnover introduce a direct security gap, not merely an operational inconvenience.
- You have a tested mechanism for maintaining continuity outside standard business hours. This cannot be a vague declaration that “someone will check their phone if something happens”, but a formalized, tested on-call rotation framework.
- Event volume and nature are predictable enough for the team to keep pace with real-time analysis without backlogs. Concurrently, the volume must be significant enough to justify maintaining dedicated investigative competencies internally rather than leaving them underutilized.
- You have the organizational bandwidth to continuosly develop team competencies. This entails tracking evolving adversary attack techniques, maintaining detection rules, and systematically learning from resolved incients.
When these conditions are met, in-house operations represent a solid strategy. Problems arise when an organization assumes it meets these criteria without rigorous validation.
What competencies does a 24/7 operations model require?
24/7 security monitoring does not simply mean hiring personnel to watch a console around the clock. It requires distinct, specialized competencies that must operate synchronously. To start, at least five key disciplines are required:
EDR/XDR platform proficiency
Deep operational understanding of how platforms like ESET Inspect classify detections, what telemetry they surface, and how to utilize their underlying rule engines.
Analytical capability
Accounts, endpoints, execution times, and event sequences – analyzed in a way that clearly distinguishes routine administrative activity from a genuine threat.
Understanding business context
Knowing which systems are critical, what operational impact a given response will have, and when a containment decision demands the involvement of stakeholders outside the technical team.
Granural reporting
The capability to accurately document incident timelines and event sequences in a manner that serves both immediate operational needs and future audit requirements.
Precision rule tuning
Based on observed false positives and emerging threat patterns, ensuring detection efficacy does not degrade as the environment evolves.
What must be considered beyond analyst headcount?
This is where planning errors most commonly occur: understanding the true financial and operational cost of running 24/7 model by merely tallying the headcount needed to fill shifts. That calculation is only the starting point…
You must factor in the time necessary to maintain and advance the team’s technical skills; tracking emerging attack techniques does not happen automatically. You must account for proxy coverage during paid time off (PTO) and sick leave. Next, add the operational hours allocated to detection engineering, periodic rule reviews, forensic report generation, and formal documentation. These essential activities are easily overlooed in shift planning, yet they consume significant bandwidth.
Long-term shift fatigue and on-call burnout must also be anticipated, as they directly drive analyst turnover. Every departure triggers a costly recruitment cycle and lenghty onboarding pipeline before full operational capacity is restored.
Furthermore, and EDR software license paired with a standard internal IT department is not equivalent to a continuous 24/7 threat investigation capability. These are two fundamentally different operational assets that are easily conflated during planning stages.
How do shift coverage, escalation, and on-call rotations work?
The operational continuity of any 24/7 framework – whether operated internally or externally – relies on mechanisms that must execute predictably.
The absence of an individual (planned or unplanned) must never create a coverage blind spot. This operational baseline requires multiple certified analysts for each role alongside an explicit protocol for shift handovers and responsibility transfers.
It defines an explicit path: who is contacted first, who is the secondary contact if the primary does not respond, and what criteria trigger an escalation to the next tier. The absence of this path introduces the risk of someone being forced to improvise in a critical moment.
Not just a schedule, but true operational readiness within the designated window – equipped with access to the necessary tools, privileges, and context to make decisions without delay.
What is the hybrid security model?
A well-architected hybrid seurity model divides responsibilities across clear, unambigous boundaries.
Time-Based Division. The internal team manages real-time monitoring and initial response during standard business hours, while an external MDR partner assumes full coverage during nights, weekends, and public holidays – the exact operational windows where running an in-house shift rotation is most cost-prohibitive.
Functional division (continuous). The internal team retains full ownership of local environmental context – defining critical asset tiers, business exceptions, and escalation frameworks. Meanwhile, routine continuous monitoring, alert triage, and initial forensic investigation are handled 24/7 by and external partner operating within strict, predefined rules of engagement.
What can MDR handle, and what must retain with the organization?
An MDR service assumes responsibility for operational elements requiring uninterrupted continuity that an individual enterprise often cannot sustain independently. It can be continuos 24/7 threat monitoring, detection triage and initial event analysis, in-depth incident investigation, threat containment within pre-agreed response boundaries, ongoing detection engineering based on real-world incident patterns.
However, there is critical institutional context that no external provider can fully replicate: granular knowledge of local architectural dependencies, business exceptions, and environment history, which uniquely belongs to the internal systems administrator. The organization permanently retains:
- Definition of critical assets and automated containment threatholds. This remains a strategic governance decision, not a purely technical choice.
- High-impact business decisions in non-standard sceratios, where localized operational priorities dictate remediation steps.
- Broader cybersecurity governance outside the direct scope of EDR – policies, network segmentation, and overall baseline IT hygiene.
The MDR model scales analytical availability and monitoring continuity where attempting in-house parity would demand resource investments disproportionate to the business’s core objectives.
Evaluating models across continuity, accountability, and operational control
Questions like “which model is cheaper?” or “which provider is best?” are unproductive at this stage. Every deplotment architecture must instead be audited across specific operational pillars.
Continuity, does this model deliver uninterrupted coverage when a key analyst takes leave, departs the company, or when an unexpected alert surge occurs? Is there a tested proxy framework in place, or merely an assumption that “things will work out”?
Accountability, is there unambiguous documentation establishing who makes cantainment decision, within what SLA timeframe, and based on what technical criteria? Is this goverance structure auditable after an event, or does it rest on informal assumptions?
Control, does the organization maintain continuos visibility into actions taken inside its infrastructure, and does it retain sovereign authority over active rules and security exceptions? A properly engineered outsourced security model operates strictly within organizational boundaries while providing total transparency into every operational action.
These criteria establish the foundation for an informed architectural decision, shifting the conversation away from superficial licensing costs or vendor marketing claims.
FAQ - frequently asked questions about EDR/MDR deployment models
Does deploying an EDR system (e.g., ESET Inspect) eliminate the need for a SOC team?
No. Endpoint Detection and Response (EDR) tooling is simply detection technology that surfaces anomalies and logs telemetry. For continuous protection, organizations require a qualified analyst team (either in-house or via MDR) capable of interpreting alerts, assessing environmental context, and executing containment measures around the clock.
When is building an internal, in-house SOC justified?
- Employs more than one cybersecurity specialist (eliminating the single point of failure risk).
- Maintains a proven, tested on-call rotation mechanism ensuring true 24/7 operational continuity.
- Experiences an event volume that justifies retaining dedicated, full-time security analysts.
- Guarantees continuous skill development for the team to keep pace with evolving adversary attack techniques.
What hidden operational costs come with running a 24/7 in-house SOC?
- Time allocated to training and continuously tracking emerging cyber threats.
- Coverage and overtime expenses during paid time off (PTO) and sick leave.
- Hours dedicated to building documentation and tuning detection rules.
- Recruitment and onboarding costs driven by staff turnover and shift-work burnout.
How does a hybrid IT security operations model work?
- Time-based division: The internal IT team monitors the network during standard business hours (e.g., 8:00 AM – 4:00 PM), while the external provider takes over monitoring at night, on weekends, and during holidays.
- Functional division: The external partner continuously monitors the environment and triages alerts, while the internal IT team – retaining deep institutional knowledge of the company’s specific architecture and exceptions – makes final business and operational decisions.
What responsibilities can an MDR service never fully offload from an internal organization?
- Defining critical assets and exceptions across the environment.
- Approving architectural and infrastructure recommendations.
- Maintaining institutional knowledge of specific business dependencies (e.g., the precise financial cost per hour of downtime for a given server).
- Overseeing baseline security hygiene and Identity and Access Management (IAM) governance.
